(c1. 665193) This invention relates, generally to rug pads such as are employed beneath oor rugs and the like to prevent slipping thereof on polished floors and more particularly to. an improved construction thereof in the form of a warpA knitted open mesh fabric, the surfaces of which are coated to provide adequate non-slippingv properties thereto.

It is an object of this inventionV to. provide an open mesh warp knitted non-slip rug padwhich will not slip on a polished floor surface and which will eifectively grip a rug placed thereon to prevent slippage of the same relative to the pad and consequently to the floor.

It is a further object of this invention to provide an open mesh. warpv knitted non-slip rug pad which may be placed on a polished oor surface and beneath a rug and which will permit air to circulate through said rug to adequately ventilate the same and prevent the,v possibility of mildew formation.

It is still a further object of this invention to provide an open mesh warp ln'iitted non-slip rug which may be placed on a polished floor surface and beneath a rug which will permit dust and` dirt to pass from the bottom of" said rug through Said pad t Said floor. thus rendering the rug substantially free from dust and dirt which would ordinarily accumulate in the bottom thereof.'

Figure l is a diagrammatic View on a somewhat enlarged scale showing a portion. of the open mesh warp-knitted fabric;- and Figure 2 is a still further enlarged view of a portion of the fabric showing. in detail the construction thereof.

Referring now to the drawings, it will be ,observed that the warp-knitted material of the present invention, a portion of which is shown in detail in Figure 2, is provided with uniformly spaced open meshes 5 of substantially quadrangular shape formed therein by a series of warpextending chain stitches 6 and a. series of weft yarns 'l extending sinuously between rows of adjacent chain stitches 6.

The weft yarns 'I are preferably of substantial thickness, while the mesh openings 5 outlined by said yarns are of substantial size. However, the present invention is not limited to any particular size of yarn and mesh opening, it being understood in this .regard that any reasonable size of the open meshes of the fabric and of the weft yarns defining the same may be employed so long as the objects of the present invention are attained.

Referring now to Figure 2, wherein the fabric of the present invention is shown on a considerably enlarged scale, it willbe observed that a plurality of separatemain body yarns 1- arev so; interlocked by an equal numbery ofA warp knit. chain stitches 6 that the said yarns extend both, weft-wise and warp-wise of the'r fabric, the por-v tions of the body yarns 7- extending'warp-wiseofi the fabric being embraced by the warp-knit chain stitchesv 6. In order to eiect this arrangement of the body yarns l, each of them is so sinn-- ously laid relatively to the warp-knit chain stitches that spaced portions thereof extend transversely or course-wise across. two or more, adjoining rows of the chain stitches, While the; intervening portions thereof extend lengthwise or Wale-.Wise of said chainstitches.

In the specific construction illustrated inli-4 ures l and 2, the course-wise portions 'la ofi each of the several body yarns 'l extend across two1 adjoining rows of the chain` stitches 6 with the. successive course-wise portions of eachsinuously laid body yarn, bound within theV chain stitches;

of every,V fourth course thereof. The` intervening,v

Wale-wise extending,v portions 1b, of each yarn are embraced by the chainA stitches formed; inf-v termediate those of every fourth. course,V these--l intermediate stitches takingy holdv of. thebody yarn portions 1b by projecting thel latter trans-V versely in one direction through one of said. intermediate stitches and then transversely in.

theopposite direction through the next, stitch,

in. the Wale-wise row of ohainstitches. Thus, the portions 1b of each body yarn extending wale` wijseof the` fabric run sinuously.y along eachI row of4 the` warp-knit chain stitches and, are firmlyI bound therein, while the course-wise extending' overlapped portions of the several yarns may be incorporated in the chain stitches of other courses depending upon the wale-wise spacing desired between the course-wise extending portions 'la of the yarns to vary as desired the size and shape of the mesh openings.

The warp knit fabric of my invention is treated with a solution of liquid latex and then subjected to a drying operation and may have more than a single treatment in order that all the component yarns of the entire fabric may be suitably impregnated with the latex which when dried forms a complete coating for all of the exposed surfaces of the fabric and of all of the yarns comprising the fabric. Instead of liquid latex, any

ion between a rug and the floor upon which it is placed. The latex or like coating may be applied in any suitable manner, as by passing c the fabric through a bath of the liquid coating material or the material may be 'sprayed upon the fabric. In certain instances, it may be desirable to initially coat the yarns with the latex or like material, preliminarily to processing the same into fabric form.

The mesh warp knit fabric of the present invention may be cut to size for use in all places where non-slip rug pads have heretofore been used, as for example, between a polished surface, such as a floor, and a rug to keep the latter from slipping. The latex-coated yarns 6 and 1 of the pad will not slip on a polished surface nor will a rug slip on the pad due to the coating of latex which is=in direct contact with the polished surface and with the rug.

In the course of normal use of a rug, the weight of persons walking thereon will cause small pants of the rug to sink into the openings 5 in the pad and thus act to effectively interengage the rug and the pad against relative movement therebetween while they remain upon the oor.

Also, in the course of normal use of a rug, a certain amount of dirt and dust settles therein and works its way to the bottom or underside thereof. When a pad of the present invention is applied beneath a rug, the dirt and dust which normally accumulates in the bottom of the rug may sift into the openings 5 of the pad, thus freeing to large extent accumulation thereof in the body of the rug itself. Further, by reason of this open mesh construction of the rug pad, relatively large air cells are provided beneath .the rug to facilitate circulation of air therethrough and so enable the rug to breathe, thus making for a healthy rug condition in general and deterring in particular to the formation of mildew in the rug.

The mesh open work warp-knit of fabric is economical to manufacture and is made in sheets which may be formed into rolls for ease in transportation and handling and from which pads of any desired size may be easily cut. Inasmuch as the fabric is formed with a large area thereof consisting of open work, it will be obvious that there is a substantial saving of material over a rug pad of solid construction, and that for a given over-all size the rug pad of the present invention will be much lighter in weight than the solid type of rug pad.

It will be understood, of course, that the inventionqherein. described 'isv susceptible of various changes and modification which may be made q from time to time without departing from the general principles or real spirit thereof, and it is accordingly intended to claim the same broadly, as well as specifically, as indicated by the appended claim.

What is claimed to be new and useful is:

A warp-knitted non-slip rug pad fabric adapted to be cut to any desired size or shape for application beneath a floor rug comprising a plurality of independent main body yarns each formed of resilient material and coated with liquid latex or the like. and a plurality of spaced rows of warp-knitted chain stitches formed of auxiliary yarns, said body yarns being each sinuously laid relatively to said rows of chain stitches so that alternate portions of each body yarn respectively extend course-wise and Wale-wise of said rows of chain stitches kwith successive course-wise extending portions of a plurality of adjoining body yarns being interlocked within a single stitch of the chain common to said successive body yarn portions, and with the successive Wale-Wise extending portions of said body yarns incorporated within the chain stitches disposed between the single stitches aforesaid, the relative arrangement of the several body yarns being such as to produce in the fabric a series of mesh openings of substantial size.
